As a drinking water system operator, your most important job is to protect the health of your customers. This Guide serves as a companion to the Basic Guide, which offers information on basic requirements that apply to all systems that add a chemical disinfectant. It contains information about: The monitoring required for disinfection byproduct (DBF) precursors; How to determine if you are in compliance; and What to report to the state and to your customers. Table 1 outlines the requirements of the regulation and the systems to which they apply. It also indicates where you can find information on each disinfectant residual, byproduct, or precursor in the Guide and its Supplements. The appendices contain examples of compliance calculations, sample monitoring worksheets, and sample monitoring plans. This Supplement does not provide information on the additional requirements for the two alternative compliance criteria available to systems using precipitative softening (i.e., lime or lime soda ash softening). If you use precipitative softening, consult your state for additional requirements and compliance options.

Some states may have additional requirements and monitoring forms. Be sure to check your state's specific requirements. For state and tribal contact information, refer to Appendices D and E. Supplement B - 4 ------- Why Do I Have to Monitor for DBP Precursors? Chemical disinfectants react with natural organic and inorganic compounds (disinfection byproduct precursors, or DBP precursors) in water to form disinfection byproducts (DBPs). Thus, reducing DBP precursors in source water will reduce the formation of byproducts in treated water. The Stage 1 DBPR addresses DBP precursors through a treatment technique (TT) requirement for Subpart H water systems that add a chemical disinfectant and use conventional filtration (40 CFR 141.135(a)(1)). The TT requirement only applies to systems with conventional filtration capability because these are typically the only systems that have the ability to reduce DBP levels in their source water affordably. Conventional filtration is a series of processes including coagulation, flocculation, sedimentation, and filtration resulting in substantial particulate removal. If you do not know whether your system uses conventional filtration, contact your state. Systems that use ground water not under the direct influence of surface water do not have to comply with the TT requirement because they usually have lower precursor levels in their source water, and systems with other types of treatment trains (e.g., direct filtration, slow sand filtration) don't have to comply because they lack sedimentation basins. A sedimentation basin at a conventional water treatment plant Supplement B - 6 ------- 6. RAA of treated water SUVA < 2.0 L/mg-m. FCC REMOVAL (40 CFR 141.135(b)) If you do not meet one of the alternative compliance criteria discussed above, you will have to meet the TOC TT requirement. Step 1 Removal Requirements Systems unable to meet any alternative compliance criterion should try to meet the Step 1 removal requirements. The Step 1 removal requirements (shown in Table 2) specify a percentage of TOC that must be removed depending on the amount of source water TOC and alkalinity. If your source water alkalinity and/or your source water TOC levels change from month to month, the percentage of TOC that you must remove may change from month to month. EPA has designed the Step 1 removal percentages to be achievable by 90 percent of Subpart H systems. Table 2: Required TOC Removal Requirements* Source Water TOC (mg/L) >2.0-4.0 >4.0-8.0 >8.0 Source Water Alkalinity (mg/L as CaCO,) 0-60 35.0% 45.0% 50.0% >60-120 25.0% 35.0% 40.0% >120 15.0% 25.0% 30.0% *40CFR141.135(b)(2) Step 2 Removal Requirements If you cannot comply with the removal requirements through an alternative compliance criteria or the Step 1 removal requirements due to water quality parameters or operational constraints, you will need to apply to the state for approval of Step 2 removal requirements. Your application to the state requesting Step 2 removal levels must include, among other things, the results of bench or pilot testing (jar testing), which is conducted according to a prescribed methodology. Using this data, the state determines an alternate enhanced coagulation level and precursor removal percentage that your system can meet. For more information on Step 2 removal requirements, see 40 CFR 141.135(b)(4) or contact your state. For information on the detailed jar testing procedures you must follow, consult EPA's Enhanced Coagulation and Enhanced Precipitative Softening Guidance Manual (EPA-815-R-99-012, May 1999), which can be downloaded at www.epa.gov/safewater/mdbp/mdbptg.htmlScoag. After the state has approved the Step 2 removal requirements for your system, you may use any coagulant and operate at any coagulant dose or pH level to achieve the specified Step 2 TOC removal percentage. Supplement B - 8 ------- How Often Do I Have to Monitor for DBF Precursors? ROUTINE MONfTORING: TOC REMOVAL (40 CFR 141.132(4X1)) All systems, regardless of compliance method, must take at least one compliance sample set every month. The sample set includes: One sample of source water alkalinity; and, One "paired sample" of TOC: one sample from the source (untreated) water, and one sample from treated water (see Table 3). The treated water sample must be collected no later than the point of combined filter effluent turbidity monitoring. The results of these samples will determine which compliance options are available to you, how much (if any) TOC you are required to remove, and how much TOC you have removed. If your source water or treated water TOC is less than 2.0 mg/L, calculated quarterly as an RAA, you do not have to remove TOC from your water because you have met one of the alternative compliance criteria. Information on how to determine compliance appears later in this Supplement, in "How Do I Determine Compliance?" REDUCED MONtTORING (40 CFR 141.132(dX2)) If your RAA of treated water TOC is less than 2.0 mg/L for 2 consecutive years or less than 1.0 mg/L for 1 year, you may reduce monitoring for the TOC "paired sample" and source water alkalinity to one paired sample and one source water alkalinity sample per plant per quarter (with prior written state approval). If your RAA ever exceeds 2.0 mg/L while you are on reduced monitoring, you must return to routine monitoring immediately.

Treated water samples should be taken after treatment but never beyond the point of combined filter effluent turbidity monitoring. The sample must be representative of treated water. Note that your state may have additional requirements for the site of the treated water TOC sample. Contact your state for more information (see Appendices D and E for contact information). Supplements-10 ------- Analysis, Compliance, and Reporting Supplements-12 ------- How Do I Determine Compliance? Systems complying through an alternative compliance criterion use their monitoring results to calculate compliance. They use monthly or quarterly results from each of the past 12 months (i.e., 4 quarters) to calculate an RAA. Using this RAA, systems can determine whether they are in compliance. Compliance determination is more difficult under the Step 1 and Step 2 removal requirements. Your removal requirements can change from month to month based on your source water characteristics. For example, changing levels of IOC in your source water may require you to remove 35.0% of TOC one month and 45.0% the following month (see Table 5). You will know whether you removed a high enough percentage of TOC each month, but you will not be able to combine individual monthly removal percentages to calculate compliance at the end of each quarter. Table 5: Required TOC Removal Requirements* To allow you to combine results and calculate an average for compliance, EPA requires that you use a ratio - the percent you actually removed divided by the percent you were required to remove - to compare removal levels and determine compliance from month to month (40 CFR 141.135(c)). Example 1, on the following page, illustrates how to calculate this ratio, and the worksheet illustrates how to calculate compliance with the Step 1 and Step 2 removal *40CFR 141-13S(6)(2) requirements using the results from your monthly sample set. Note how the required removal percentages (which are for Step 1 compliance in this example) change from month to month based on the source water characteristics, and how the results affect the removal ratio used to calculate compliance. Table 6 summarizes how to determine compliance for Step 1, Step 2, and alternative compliance criteria. Source Water TOC (mg/L) >2.0-4.0 >4.0-8.0 >8.0 Source Water Alkalinity (mg/L as CaCO,} 0-60 35.0% 45.0% 50.0% >60-120 25.0% 35.0% 40.0% >120 15.0% 25.0% 30.0% Supplements-14 ------- The system has fallen below the compliance removal ratio of 1.00, but since compliance is based on an RAA, calculated quarterly, the system has not yet committed a violation. Required TOC Removal Requirements* In November of 2004, the characteristics of the system's source water change: its source water TOC is now 3.2 mg/L and its source water alkalinity is now 61 mg/L. The required removal percentage for the month of November is 25.0% (see table at right). The treated water TOC sample is 2.3 mg/L, so the percentage of TOC removed is 28.1%, yielding a removal ratio of 28.1/25.0, or 1.12. The system continues to collect samples each month. At the end of each quarter, the system calculates its RAA based on results on this worksheet and data from previous quarters not shown here. Source Water TOC (mg/L) .|%$J£lfr'f >4.0-8.0 >8.0 Source Water Alkalinity (mg/L as CaCO,) 0-60 '$*#* 45.0% 50.0% Slpif -ife^p;-- Zd.UTO ' 35.0% 40.0% >120 15.0% 25.0% 30.0% *40CFR141.135(b)(2) In April of 2005, the system's treated water TOC is 1.9 mg/L. Since having treated water TOC lower than 2.0 mg/L is one of the alternative compliance criteria (criterion 2), the system will not have to meet the Step 1 TOC removal percentage for the month and can instead use a 1.00 for the removal ratio. Note that if the system tried to calculate a removal ratio using the required percentage (25.0%) and the percentage removed (9.5%), it would not meet the required removal ratio for the month. By allowing systems to use 1.00 as a removal ratio in this situation, the Rule contains built-in flexibilities to help systems comply with the TT requirements through more than one option. In September of 2005, the system calculates its RAA of removal ratios using its removal ratios for the last 12 months (all shown on this worksheet): 0.41 + 1.12+ 1.33 + 1.07 0.57-1-1.0 + 0.87 + 0.76 + 1.53 + 1.74 12 = 1.06(^1.00) The system's RAA is above the required compliance removal ratio of 1.00. The system is in compliance. Supplement B-16 ------- Table 6: Determining Compliance For Systems Meeting the: Step 1 and Step 2 TOC Removal Requirements Alternative Compliance Criteria Compliance is based on: An RAA of monthly ratios (i.e., the ratio of actual TOC percent removed to required TOC percent removed), computed quarterly (see worksheet on page 1 6 for details on how to calculate).

All PNs for must include the following specific health effects language (40 CFR Subpart Q, Appendix B): TOC: "Total organic carbon (TOC) has no health effects. However, total organic carbon provides a medium for the formation of disinfection byproducts. These byproducts include trihalomethanes (THMs) and haloacetic acids (HAAs). Drinking water containing these byproducts in excess of the maximum contaminant level (MCL) may lead to adverse health effects, liver or kidney problems, or nervous system effects, and may lead to an increased risk of getting cancer."

Supplement B - 22 ------- Appendix A: Sample Monitoring Worksheet The following worksheet is designed to help you keep track of your Stage 1 DBPR sampling and results. The worksheet is designed to allow you to record both the results from your routine monitoring and your compliance calculations. While the worksheet may be a useful management tool, system operators should also keep the original laboratory results on file. You can photocopy the blank worksheet so that you have blank worksheets to use in the future. The worksheet can help you ensure that you collect the right number of routine samples in each monitoring period and that you calculate compliance correctly. The worksheet will also remind you of corrective actions you will have to take if you violate the TT. The worksheet includes an explanation of how to complete it and how to use it to calculate compliance. Review the example on pages 14-16 to help you understand how the worksheet would be used in a real-world situation. Some states may have their own monitoring worksheets that small community drinking water systems are required to complete. The worksheet contained in this section is presented as a learning tool and should not replace monitoring forms required by the state. Supplement B - A-1 ------- DBF Precursor Monitoring Worksheet PI (a) Note: Al systems must coded a sample of raw water alkalinity and a paired TOO sample each month, regardless of the compliance criterion the system is using. (b) The required TOC removal percentage can be read from Table 5 based on the sample results for source water TOC and alkalinity. Supplement B - A-3 ------- Monitoring Plan Example #1: A Subpart H System Using Conventional Filtration Green Acres, a Subpart H system using conventional filtration and chlorine for disinfection, was required to develop and maintain a monitoring plan and make it available for state inspection by January 31,2004. The operator of the system, Bob Waters, completed a monitoring plan that includes an overview of system characteristics as well as individual monitoring schedules for the disinfectant (chlorine), disinfection byproducts (TTHM and HAAS), and DBP precursors (measured as TOC). This plan presents basic system information and describes where and when the system collects its samples and how it determines compliance with the MCLs, MRDLs, and TT requirements. To develop the plan, operator Waters entered system contact information, including the system's name and address, and the operator's phone number and email address. This information can be useful for state officials or customers who need to contact the system. Next, the operator entered the number of customers (1,350) and the number of service connections (495) Green Acres serves. This information can help state officials who are unfamiliar with the system determine the Stage 1 DBPR requirements that apply to the system. Next, the operator entered the system characteristics, including the type of system (CWS) and types of disinfection and filtration (conventional filtration and chlorination). All of these determine that Green Acres is required to monitor for chlorine, TTHM and HAA5, and DBP precursors. The operator then made note of the system's source water characteristics. This will give the state a better understanding of how the system operates, when the system is in operation, and how the system's source water characteristics affect its Stage 1 DBPR compliance requirements. This information is also useful should Green Acres hire a new operator who is less familiar with the system. Green Acres draws its water from one source, the Green Acres River. The system uses conventional filtration and chlorination at its one treatment plant.
